SPECIFICATION forming part of Letters Patent Nag. 389,188, dated September 11, 1888. Application filed November 28, 1884. Serial No. 149,120. (No model.)

T o aZZ whom, it may concern: I

Be it known that we, JAMES H. BARLEY and THOMAS K. BARLEY, citizens of the United States of America, residing at Sedalia, in the county of Pettis and State of Missouri, have jointly invented certain new and useful Improvements in Harrows, of which the following is a specification, reference being had therein to the accompanying drawings, making part of this specification, in which like letters of reference refer to like parts, and in which drawings- Figures 1 and 2 are side elevations or face views of portions of a harrow-tooth bar or rail, showing our improved tooth pivotally attached thereto and supported at different angles; and Figs. 3 and 4 are views of the tooth-supporting bar or rail in vertical crosssection, with the teeth attached thereto. Fig. 5 is a view of the tooth in cross section, and Fig. 6 is the tooth in side elevation before the side projecting heads are formed thereon. Fig. 7 is a longitudinal side sectional View of our improved spacing bracket or spool, top downward having a portion of a clamping-bolt in place. Fig. Sis a plan top view of same. Fig. 9 is an end or cross-sectional view ofa harrowseetion as formed with three tooth bars or rails. showing the spacing bracket or spool inserted between said rails, and are clamped together by a screw-bolt passing through the rails and bracket. Figs. 10 and 11 are views of the bracket or spool in cross-section. Fig. 12 is a top or side view of the clampinglink, show ing tooth and edge of rail in dotted lines. Fig. 13 is a view of a two-prong fastening-key which passes through the point end of the clamping-link.

Our invention relates to certain new and useful improvements in that class of field dragharrows provided with self-adjusting teeth; and it consists, first, in the combination of a self-adjusting harrow-tooth and rail, said tooth pivotally attached thereto and having a side projecting head formed integral with its upper end and adapted to rest on the upper edge of said rail, whereby said tooth is supported at different angles.

Second. It also consists in a selfadjusting 5o barrow-tooth having a perforation between its point and head adapted to receive a metal pivot which forms the lower support for said tooth, and having lateral projecting toothsnpports formed integral with one or both sides of its upper end and adapted to rest on the top edge of the bar or rail which forms the upper support for said tooth.

Third. It further consists in aself-adjusting harrow tooth having integral supports for said tooth, formed projecting laterally on one or both sides of its upper end, and having a perforation between the point and head, and an edge bend at or near said perforation to operate as hereinafter more fully described.

Fourth. It further consists in an improved clamping-link by which the barrow-teeth are pivotally attached to the tooth supporting bars or rails and securely held in place.

Fifth. ()ur invention further consists in the novel construction of a metal bracket or spool for holding the tooth supporting bars or rails at suitable distances apart in forming the barrow-sections.

Sixth. It also consists in certain novel constructions and combination of parts, as will be hereinafter more fully described, and pointed out in the claims.

In the drawings, A designates portions of a barrow tooth bar or rail having the teeth B pivotally attached thereto, said teeth having side or lateral projecting heads B, bent or forrrel at their upper ends.

B represents a perforation or countersink formed in said tooth, between its point and head, through which a metal pivot may be passed, and through corresponding perforations in the sides of said bars or rails with the side projecting heads B resting on the top edge thereof, allowing the tooth having a horizontal movement on its pivot and supported at different angles when the motion of the harrow is reversed to the opposite direction, as shown in solid and dotted lines, drawings Figs. 1 and 2. The outer ends of the side projecting heads B of said teeth may also be bent,

forming lips B, extending down a short dis tance over the opposite side surface of the upper part of said bars or rails forming side supports for the teeth, thus relieving their connecting-pivots from any liability of breakage when undue strain is brought against their lower portions, as shown at drawing Fig. 3.

If preferred, the teeth may also have an edge bend at or near their connecting-pivots B, as shown at drawings Figs. 1 and 2, for the purpose of more or less equalizing the longitudinal distance the upper bent heads 13 of said teeth rest on the top part of the bars or rails A at points forward and in rear of their connecting-pivots on which the teeth turn, and at the same time maintain the same angle or inclination of the lower portions of said teeth.

At drawing Fig. 12, O is a link shaped clamp, which may be used for attaching the teeth to the bars or rails, in lieu of a metal pivot passing through said tooth, as before mentioned, said clamp being passed over the tooth with the V-shaped pivot-point 0 provided on its inner part, fitting in a countersink, B, in the tooth forming the lower support and pivot for said tooth, the rear or outer end, 0 of said clamp extending through a perforation in the rail A, and receiving a key which is passed through the opening 0" thereof; or any other suitable device may be applied to the end (3 of said clamp to hold the tooth in place.

The teeth B may be formed as shown at' drawings Figs. 5 and 6, having flat bearing sides B, and two convex or oval cutting-edges, B, which are set to run in a direct line of draft. It is obvious that a tooth thus formed will be greatly strengthened and less liable to get bent or broken.

E is our improved bracket or spool for harrows,the novel construction of which is shown at drawings Figs. 7, 8, 9, 10, and 11, and is placed between the toothsupporting bars or rails A, with their ends resting against the side surfaces thereof, and having a screw'bolt passing longitudinally through said bracket and through the sides of said bars or rails, clamping them together, forming the harrowseetions, as shown at drawing Fig. 9. Said bracket or spool may be formed of either cast, malleable, or wrought metal, as shown at said figures, the novel construction of which, consisting of the self-retaining loop-bar E, (having each of its ends-formed integral with the side portions, 12",) projecting a sufficient distance beyond the central portion of said bracket, forming a longitudinal opening, E, and also side and end openings E are produced without using dry-sand cores to form the first-named opening when said bracket is made by a casting process, and when made of wrought metal the self-retaining loop-bars E are readily pressed or bent down from the top portion, 113, projecting transversely beyond the central portion of said bracket, forming corresponding side and end openings, E extending back from one or both of its ends a longitudinal distance about the same as the width of said loop-bars E*, which, having suflicient space left between its inner portion and the inner top or body part E thereof (when made of either cast or wrought metal) to admit the clamping screw-bolt F passing longitudinally through the opening E in said bracket, as shown at drawings Figs. 7, 8, 9, and 10, whereby they 'are kept in place between the tooth-rails should the clamping screw-bolt become slackened.

Drawings Figs. 8 and 11 show the retaining-loop bars E removed, leaving the end of the bracket open, but shown in dotted lines, Fig. 11. The longitudinalshapeofsaid bracket may be varied somewhat from the form shown in cross-section, where the sides E converge upward from the base, forming an arch or oval shaped top; or said top may be made flat or nearly so.

Ve do not, broadly, claim the sole use of a metal spacing bracket or spool inserted between the harrow-toothsupporting bars or rails, as we are aware they have been used prior to our invention.

. Having fully described our invention, what we claim as new and useful, and desire to secure by Letters Patent, is-
